Definitions

  • the invention relates to an intake system for internal combustion engines with resonance chambers with a natural frequency that can be continuously adjusted automatically as a function of the speed of the internal combustion engine in order to utilize vibrations for a moderate supercharging of the internal combustion engine.
  • DE-AS 10 49 149 describes a resonance system that must be attached to the internal combustion engine in addition to the usual intake system and is also only effective at precisely defined frequencies since it has a separate resonance chamber for each frequency.
  • the positive effect of resonance charging is therefore not available over the entire speed range, but is limited to a few specified speeds.
  • the system described in DE-PS 15 76 022 does not have this serious functional disadvantage.
  • the continuous speed-dependent adjustment with an elaborate rule is used system bought.
  • the hydraulic system required to operate the system is relatively expensive and again requires additional installation space.
  • the object of the invention is to provide an intake system whose natural frequency is continuously adjustable, so that the effect of resonance charging can be used over the entire speed range, but which at the same time has to be inexpensive to manufacture and takes up only an insignificant additional space.
  • this object is achieved in that the intake system automatically adapts to the respective speed of the internal combustion engine by changing the volume of the collecting tubes serving as resonance spaces as a function of vacuum.
  • This is achieved in that at least one end wall of each manifold is designed as a displaceable piston which is deflected inwards by the negative pressure in the intake pipe.
  • this piston is connected to a damping element which prevents the system from reacting to individual pressure or vacuum peaks, since the piston could otherwise perform an oscillating movement even at a constant engine speed.
  • the piston and damping element are advantageously combined to form an assembly that can be completely replaced, e.g. a shock absorber element.
  • a stop is provided in the resonance chamber to limit the deflection of the piston.
  • the damping element serves as a stop and the housing of the damping element is thereby overloaded.
  • the resonance charging only becomes effective up to a defined limit speed, which helps to avoid overspeeding of the engine.
  • the housing of the damping element on the side facing away from the piston with an external thread which engages in an internal thread which is provided on the front opening of the collecting tube for inserting the natural frequency adjusting element. This ensures simple and secure attachment as well as easy assembly and disassembly.
  • An intake system is usually composed of three components, namely the manifolds 1, the intake pipe 2 and the intake pipes 3 for the individual cylinders.
  • Fig. 2 it can be seen how a complete assembly of adjusting element and damper is installed in a manifold 1.
